1. A method of forming an adhesive, the method comprising:

  • providing a composition comprising at least one monomer, a first actinic radiation initiator, and a second actinic radiation initiator, wherein the second initiator is substantially non-photoactive at activation wavelength(s) of the first initiator;

    at least partially polymerizing the composition by exposing the composition to radiation comprising wavelengths corresponding to the activation wavelength(s) of the first initiator;

    at least partially crosslinking the composition to thereby form the adhesive by exposing the composition to radiation comprising wavelengths corresponding to the activation wavelength(s) of the second initiator;

    wherein at least one of the first and the second initiators is a polymerizable monomer containing a photoinitiator moiety.
